Shall I remove it? I think that we don't provide any promises about typing.py internals.

Shall I remove it?

Sounds good to me! This is undocumented, untested, not included in __all__, and has a name starting with a leading underscore. I don't think we can be any more explicit about the fact that it was an internal implementation detail 😆
